IntelliJ IDEAIDEA缓存

intellij IDEA在第一次启动时，会在${user.home}目录下建立以.IntelliJIdea开头的文件夹，用来存放IDEA的配置信息、插件和缓存信息。随着工具使用时间越多，这个文件夹会越来越大。如果用户目录和系统盘在一个分区，那系统盘分区可用空间就会变小，系统重装时，这个目录还会被删除。

于是我们需要将此目录修改到其他分区，修改很简单，如下：

在IDEA安装目录的bin文件夹中找到idea.properties文件，我们需要里面的几项内容：

1. # Use ${idea.home} macro to specify location relative to IDE installation home.
2. # Use ${xxx} where xxx is any Java property (including defined in previous lines of this file) to refer to its value.
3. # Note for Windows users: please make sure you're using forward slashes (e.g. c:/idea/system).
4. #---------------------------------------------------------------------
5. # Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.
6. #---------------------------------------------------------------------
7. #打开confi的配置
8. # idea.config.path=${user.home}/config
9. #---------------------------------------------------------------------
10. # Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.
11. #---------------------------------------------------------------------
12. #打开system的配置
13. # idea.system.path=${user.home}/system
14. #---------------------------------------------------------------------
15. # Uncomment this option if you want to customize path to user installed plugins folder. Make sure you're using forward slashes.
16. #---------------------------------------------------------------------
17. #打开plugins的配置
18. # idea.plugins.path=${idea.config.path}/plugins
19. #---------------------------------------------------------------------
20. # Uncomment this option if you want to customize path to IDE logs folder. Make sure you're using forward slashes.
21. #---------------------------------------------------------------------
22. #打开log的配置
23. # idea.log.path=${idea.system.path}/log

# Use ${idea.home} macro to specify location relative to IDE installation home.
# Use ${xxx} where xxx is any Java property (including defined in previous lines of this file) to refer to its value.
# Note for Windows users: please make sure you're using forward slashes (e.g. c:/idea/system).

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
#打开confi的配置
# idea.config.path=${user.home}/config

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
#打开system的配置
# idea.system.path=${user.home}/system

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to user installed plugins folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
#打开plugins的配置
# idea.plugins.path=${idea.config.path}/plugins

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE logs folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
#打开log的配置
# idea.log.path=${idea.system.path}/log

将idea.config.path和idea.system.path里面的${user.home}改成将要存放目录的位置，我这里修改为D:/Program/JetBrains，如下是修改后的结果

1. #---------------------------------------------------------------------
2. # Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.
3. #---------------------------------------------------------------------
4. idea.config.path=D:/Program/JetBrains/.IntelliJIdea/config
5. #---------------------------------------------------------------------
6. # Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.
7. #---------------------------------------------------------------------
8. idea.system.path=D:/Program/JetBrains/.IntelliJIdea/system

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE config folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
idea.config.path=D:/Program/JetBrains/.IntelliJIdea/config

#---------------------------------------------------------------------
# Uncomment this option if you want to customize path to IDE system folder. Make sure you're using forward slashes.
#---------------------------------------------------------------------
idea.system.path=D:/Program/JetBrains/.IntelliJIdea/system

 注意：一定要将配置项前面的注释符（#）去掉，否则不生效。

接下来，重启IDEA工具就可以了。
